Spider combs tame unruly nanofibers

Cribellate spiders spin thousands of tiny nanofibers
into sticky threads. To keep from getting caught in their own webs,
these spiders use a nonstick comb on their back legs. Now,
researchers reporting in ACS Applied Nano Materials have patterned
an antiadhesive nanostructure inspired by this comb onto a foil
surface, creating a handy tool to control sticky lab-made
nanomaterials for medical, smart textile and other applications.
